When in doubt, Gaffey recommends going “more pared-back but polished” with sleek, sophisticated pieces. She also suggests solid colors that can be elevated with accessories over statement fabrics and patterns. “A statement earring, chunky cuff, or party-ready clutch will add a fun feel to office-appropriate pieces.”

Singla tells InStyle her choice for a business cocktail event would be “a long-sleeve cashmere knit dress in a dark shade of gray or deep black, paired with tall black stiletto boots.” The rich blend of materials, fabric, and leather, she says, creates a look that is chic, sophisticated, and appropriate for the occasion.

According to Witt, business cocktail attire alludes to maintaining somewhat of a professional air (a.k.a. showing less skin) while cocktail attire is traditionally a little sexier. But luxe fabrics are still fair game. For instance, a silk maxi skirt paired with a crisp white shirt and statement jewelry or a dainty dress with an oversized blazer over the shoulders “strikes a great balance,” says Witt. She recommends brands like Stella McCartney, Alaia, Christopher Esber, and Magda Butrym.

A matching set makes for foolproof dressing. This tailored iteration is office-friendly and it packs way more visual interest than if you were to recreate the look with separates. The slit also helps it from feeling too stiff and patent leather Mary Janes with a block heel add a fun, trendy twist.

If you don’t feel comfortable in dresses or skirts, Gaffey says tailored, high-waisted trousers or a jumpsuit would adhere to business cocktail dress codes. Plus, they’re what Gaffey calls “day-to-night saviors” because “they can be swiftly switched for an evening event with a quick addition of accessories if you're coming straight from the office.”

Oftentimes, people will confuse “business” with “stuffy,” but you can have fun and be stylish at a business cocktail event. A professional strategy to achieve this is to mix and match your materials. “Wear a monochrome look complete with black wool trousers, a silk blouse, and a cashmere cardigan with a pair of suede kitten heels,” Singla recommends. “By mixing materials, the look feels versatile and modern.”

According to Singla, business cocktail attire is a more conservative way of dressing for work-adjacent events. ”The primary color scheme for this type of ensemble is neutrals in the form of classic suits and separates, and more tailored looks are appropriate, though you can add elements of interest like unique accessories and pops of color,” Singla says. The pink and red combo here is a great example.

Dressing for a business cocktail occasion doesn't mean you have to be covered up from head to toe. Instead, be strategic. If you choose to go sleeveless, find balance with a high neckline and a maxi hemline. If you opt for a slit, make sure it doesn't go much higher than your knee.

You can't go wrong with an LBD, but Gaffey tells InStyle you want to “choose an interesting silhouette or texture while still keeping it appropriate.” Or, if black feels too formal, Gaffey goes on to suggest widening the color net with rich berry, burgundy, forest green, or jewel tones.
